Effects of repetitive transcranial magnetic stimulation on electroencephalographical measures of poststroke upper limb dysfunction: study protocol for a randomized controlled trial.
Article in Trials, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPatients with stroke would experience upper limb dysfunction, leading to functional impairments in daily living and placing a burden on society and families. Repetitive transcranial magnetic stimulation (rTMS), a noninvasive neuromodulation tool, has been shown to upper limb dysfunction. However, the clinical efficacy and the underlying neurophysiological mechanisms of optimal intensity of rTMS to promote motor recovery of stroke patients with upper limb function need further investigations. This study aims to investigate the changes in the brain neurophysiological mechanisms ranging from cortical oscillatory activity to the effectiveness of the complex network after low-frequency (LF) and high-frequency (HF) rTMS on motor areas of patient post-stroke.
methodA total of 42 stroke patients with upper limb dysfunction will be randomized into high-frequency (HF) rTMS group and low-frequency (LF) rTMS group (1:1 ratio). The HF-rTMS group will use 90% resting motor threshold (RMT), 10 Hz acting with the ipsilesional M1 for a total of 1500 pulses for 2 weeks, and the LF-rTMS group acting on the contralesional M1 with the same parameters, except that 1 Hz is used. The National Institutes of Health Stroke Scale (NIHSS), the motor deficit (the Fugl-Meyer Assessment Upper Extremity (FMA-UE)), Modified Barthel Index (MBI), and resting-state electroencephalogram (EEG) signals will be obtained at the baseline and within 1 week after the rTMS. DISCUSSION: This study will contribute to the understanding of the neurophysiological changes in the brain corresponding to the clinical effects of HF- and LF-rTMS in patients with stroke.
